6. Manual Graphing
k Graphing in the Run-Matrix Mode
While the Linear input/output mode is selected, commands can be input directly in the Run-
Matrix mode to draw a graph.
You can select a function type for graphing by pressing !4(SKETCH)5(GRAPH) and
then selecting one of the function types shown below.
• {Y=}/{r=}/{Param}/{X=}/{G ·
function}/{X=
• {Y>}/{Y<}/{Y≥}/{Y≤} ... Inequality {Y>
• {X>}/{X<}/{X≥}/{X≤} ... Inequality {X>
• Graphing with Rectangular Coordinates
1. From the Main Menu, enter the Run-Matrix mode.
2. On the Setup screen, change "Input/Output" setting to "Linear".
3. Configure V-Window settings.
4. Input the commands for drawing the rectangular coordinate graph.
5. Input the function.
